WNT(i)
12 So after He had washed their feet, put on His garments again, and returned to the table, He said to them, "Do you understand what I have done to you?
13 You call me 'The Rabbi' and 'The Master,' and rightly so, for such I am.
14 If I then, your Master and Rabbi, have washed your feet, it is also your duty to wash one another's feet.
